all common ones .Condition and history of car may help decide direction start looking at things.Does it have running issues ! do these codes come back once cleared !If had recent engine pull/work then wiring harness, grounds and connector plugs to sensors for damage good first visuals.If things all tidy then basic tests on knock sensor and ecu temp sensor good place start. Is lot of threads on ecu temp and knock sensor, you can also easily supplement these with resistors which help pinpoint sensor fault over wiring quickly and low tech/cost .MAF maybe harder pinpoint fault and only expensive sensor out of the 3 but again few threads and FSM tests you can do and all 3 maybe power/ground/wiring issue anyway .good luck .
